Die Informationen oben werden nun gebraucht. Die Konfiguration sollte geprüft werden, nicht das bereits ein LVM für das Storage vorgesehen ist.

Schritt 2 - Anlegen einer neuen Partition

Hier ist es erforderlich, dass man weiß, wo der zusätzlicher Platz zu finden ist. Es gibt 2 Varianten - entweder eine neue Platte, oder eine erweiterte Platte.

In beiden Fällen, wird eine neue Partition angelegt. Hier in diesen Beispiel, wurde eine neue Platte genutzt, die auf /dev/sdb zu finden ist.

...

Partitionierung mit

The information above is now needed. The configuration should be checked, maybe an LVM is already planned for the storage.

Step 2 - Create a new partition

Here it is necessary to know where to find the additional space. There are 2 variants - either a new plate, or an extended plate.

In both cases, a new partition is created. Here in this example, a new disk was used, which can be found on /dev/sdb

Adjust the commands below and the partition number (for an existing disk, the partition is then no longer necessarily 1) accordingly.

In beiden Fällen, wird eine neue Partition angelegt. Hier in diesen Beispiel, wurde eine neue Platte genutzt, die auf /dev/sdb zu finden ist.

Créer le magasin avec LVM

La plupart de nos installations Linux / CentOS fonctionnent avec LVM. Ce guide décrit comment installer le rôle MAGASIN sur un système utilisant LVM.

Étape 1 - Détermination de la configuration actuelle

Translations Ignore

Code Block

language	bash
title	Affichage de disques

# Show free space df -h # Show partitions fdisk -l # Show partitions ls /dev/sd* # If the disk cannot yet be seen, re-scan the SCSI bus echo "- - -" > /sys/class/scsi_host/host0/scan # View physical volumes managed by LVM lvm pvs # Display logical volumes managed by LVM lvm lvs # Display logical volume groups managed by LVM lvm vgs # Where is what mounted mount

Les informations ci-dessus sont maintenant nécessaires. La configuration doit être vérifiée, peut-être qu'un LVM est déjà prévu pour le stockage.

Étape 2 - Créer une nouvelle partition

Ici, il faut savoir où trouver l'espace supplémentaire. Il existe 2 variantes : soit une nouvelle plaque, soit une plaque étendue.

Dans les deux cas, une nouvelle partition est créée. Dans cet exemple, un nouveau disque a été utilisé, qui peut être trouvé sur /dev/sdb

Ajustez les commandes ci-dessous et le numéro de partition (pour un disque existant, la partition n'est alors plus nécessairement 1) en conséquence.

Étape 3 - Inclusion dans LVM - Créer un Appareil

language	bash
title	Créer un appareil pour LVM

# Here is the previous edition of /dev/sd* --> this is the new record (the 1st partition on /dev/sdb, i.e. the second hard disk, newly created partition) lvm pvcreate /dev/sdb1

Étape 4 - Créer un groupe de volume

Étape 6 - Création d'un système de fichiers

Étape 9 - Vérification du résultat interime

Il devrait y avoir une entrée pour /srv/jtel/shared avec l'espace libre correspondant.

Configuration de SeLinux, jtel Accès utilisateur et pare-feu pour Samba

Remplacez <password> par le mot de passe de l'utilisateur de jtel :

Si nécessaire, ajoutez d'autres utilisateurs à samba - en remplaçant le mot de passe par le mot de passe réel de l'utilisateur. Ici, par exemple, l'utilisateur administrateur de Windows :
